Get pistons, rings, and wrist pins in one affordable package with Wiseco Pro Tru kits.

Ideal for sportsman racers on a tight budget, these Wiseco Pro Tru kits give you high-quality racing pistons, rings, wrist pins, and Spiro locks in one affordable package. The pistons feature CNC-machined domes, oversized valve pockets for use with larger diameter valves and higher lift camshafts, and precision-reamed, pressure-fed wrist pin oiling holes. The Hastings piston rings are a high-tensile strength design featuring a plasma-moly coating to eliminate fracturing, while providing superior protection against oil blowby. Last, but not least, the wrist pins are made from chromemoly for long-lasting strength and include a set of Spiro locks to keep them where they belong.
